fix: show logs for tasks killed by runtime without finished_at

Tasks killed by Titus (OOM, eviction, etc.) never write the attempt-done
metadata record, leaving finished_at null. The UI gated log fetching on
finished_at being set, so logs were silently never fetched even when they
existed in S3.

Fix: treat any terminal task status (completed, failed, unknown) as
"finished enough" to fetch logs, regardless of finished_at.
